CORN-PLANTER.

SPECIFICATION forming part of Letters Patent N 0. 678,900, dated July23, 1901.

Application filed March 12, 1901- T 0 all whom, it may concern.-

Be it known that 1, PETER A. PETERSON, a citizen of the United States ofAmerica, residing at Lake Mills, in the county of Winnebago and State ofIowa, have invented certain new and useful Improvements inCorn-Planters,of which the following is a specification, reference beinghad therein to the accompanying drawings.

This invention relates to corn-planters, and particularly to that classknown as the checkrow type.

The object of the invention is to produce a corn-planter in which thefeeding mechanism of the hopper is actuated through the medium of areciprocating flexible connection extending from one side of the planterto the other.

Furthermore, the object of the invention is to produce actuating meanswhereby as the planter is drawn forward the feeding mechanism isintermittently operated.

Furthermore, the object of the invention is to produce a corn-planterwhich will possess advantages in points of efliciency and durability,proving at the same time comparatively inexpensive.

With the above and other objects in view the invention consists in thedetails of construction and in the arrangement and combination of parts,to be hereinafter more fully set forth and specifically claimed.

In describing the invention in detail reference will be had to theaccompanying drawings, forming a part of this specification, whereinlike characters denote corresponding parts in the several views, andinwhich- Figure 1 is a top plan view of a planter embodying the invention.Fig. 2 is a view in side elevation. Fig. 3 is a view in elevation of thefeeding mechanism.

In the drawings, 1 denotes the seedboxes, 2 the furrow runners oropener, and 3 the front beam, which may be of any ordinary construction.A beam 4 is supported at the rear of the runners. The beams 3 and 4 areconnected by curved brackets 5, forming a front frame for supportingparts of the seeding mechanism. Arms 6 are bolted to the front beam 3and carry pulleys 7, over or Brackets 9 are secured to the brackets 5,and yoke-like trips 10 are hung on the bolts 11.

Serial No. 50,874. (No model.)

The trips are approximately U shape and have secured thereto arms 12,having eyes 13 in their upper ends through which the cable runs, saidcable being provided with balls 14, which engage the arms and cause theyokes to swing. One end of each yoke is extended and provided with aneye 15, to which a link 16 is pivoted. The link is pivoted to thecranked end of a rock-shaft 17, and the rockshatt 17 carries an arm 18,connected to the feeding-rod 19 of the hopper. As the yoke is swung,therefore, through the action of the balls on the cable the feeding isreciprocated. The wheels 20 are mounted on an axle 21, and the frame 22is secured to the axle in any convenient manner. The front end of theframe is pivotally connected to the arms 23 on the beam 4 of the frontor runner frame.

On each side of the planter I provide parallel guides, each set ofguides comprising two upper and two lower metallic strips 24 and 25,respectively, the strips 24 and 25 on each side being rigidly connectedand supported by brackets 26, joined to the frames. Standards 27 aresecured to the frames and have angular ends extending out over thewheels. A guide is formed on the end of each standard by the plates 28and 29, which are connected by bolts 30, and the bolts each have anantifriction-sleeve 31 mounted thereon.

Levers 32 have the ends of the cable at tached and reciprocate inalternate directions as the planter is drawn forward. The lower end ofthe lever is provided with a prong 33,

projecting below the end of the lever. 34 is connected to each lever,and a pin 35 projects on each side, said pin riding in the edges of theguides 24 and 25 as the lever reciprocates. A spring 36 extends from thepin 35 to a log 37 of the lever, so that as the pin rides over theguides a yielding action is af- A link posed lever descends into theground the pin 35 on the rearwardly-disposed lever passes the point 38and owing to the pull on the cable the said pin rides over the inclinedend 39 and is drawn back on the upper edges of the guides 24. Thedepending arms 40 limit the rearward movement of the lever, and the arms41 limit the forward movement thereof.

From the foregoing it will be seen that the anchored lever pulls the onewhich is released through the medium of the cable, and as said cable hasthe tripping-balls thereon the feed-j ing is operated. It will beobserved also that as the lever is inclined rearwardly it will have atendency to rise to and travel on the surface of the ground, so that thepull required to bring it up the inclined surface to theuppejr'edg'e-ofthe guid'es will be inco'n'sid'erable.

Having thus fullydescribed the invention, what I claim as new, anddesire "to secure by Letters Patent, i's-r- 1; In acorn-planter,a'suitable frame, feedmg mechanism, acable for'actua'tin'g the feedingmechanism, levers to which the cable is secured and means for causingthe levers to move longitudinally and vertically of the planter.

2. In a corn-planter, a suitable frame, feeding mechanism carriedthereon, a cable for operating the feeding mechanism, guides on eachside over the frame, levers having pins riding over the guides, and armsat each end of the guides to limit the travel ofv the levers, sub-
